Bryan, Problem solved. At your suggestion, I installed MARC::Record 1.39_02, and it's working fine.
I was wrong about having installed version 2.0 in the past. When I looked at my old notes, I saw that I wasn't able to install version 2.0 because of Perl 5.8.0. - which makes sense. That's what I get for leaving a tarball of Marc::Record 2.0 in my backup directory (:->) Thanks again for your help! - Chris
